Poor computer posture can lead to repetitive strain injuries. When you sit with the head forward, shoulders hunched, and wrists bent awkwardly during long typing or mouse use, the same small movements repeat over and over. This puts continuous stress on the muscles, tendons, and nerves in the neck, shoulders, arms, and wrists. Over time, this strain can cause inflammation, pain, numbness, or tingling—classic signs of RSI. Keeping a neutral wrist position, elbows at a comfortable angle, the monitor at eye level, and using a chair with good back support, along with regular breaks to stretch, helps prevent RSI. The other options aren’t risks or describe improvements that come from better posture, so they don’t fit the situation.
